They can't change federal laws, but they can add to them.

Federal says "You have to have at least two rear facing mirrors".

State XYZ says "We agree, but we also want to add to it that you have to have three."

They didn't change the original law of "at least two". They just raised their local minimum, which is still in compliance with the federal regulation.
